VALVE LOCK FOR AUTOMOBILES.

Application filed February 28, 1920,;Seria1 N0. 362,053. i

To all whom it may concern.

Be it known that I, GEORGE H. HARRIS, a citizen of the United States, residing at Utica, inthecounty of Oneida and State 'of New York, have invented certain new vthroughout the specification.

The object of the invention is to provide a device for locking an automobile, while standing temporarily by the side of the road or curb, whereby to prevent the theft thereof. The locking is efiected by inserting a rotary valve between the carburettor and manifold intake, so as to intercept or out oi the passage of gas from entering the en-.

gine, while so standing. A Yale or other similar lock is employed to retain the valve in closed position. Inthis manner, the automobile can be left standing without fear of molestation byunauthorized persons .or miscreants.

The object will appear by referring to the drawings, in Which:

Fig. 1 is a vertical section of the rotary valve and immediate parts;

Fig. 2 is a section taken on the line 22 of Fig. l;

. .Fig. 3 is a perspective view of the-rotary valve;

Fig. 4 is an enlarged detail view of a looking bolt employed; 7

Fig. 5 is an enlarged detail view of a Yale lock employed;

Fig. 6 is a detail View, showing a perspective of an annular rin employed.

Fig. 7 is an elevationa view, showing parts broken away of a modification of the device.

Referring more particularly to the drawings, the plpe or conduit leading from the carburetter of an automobile is represented :sai'd carburettor andmanifold intake-is disposed a valve casingii in which rests a rotary valve 4. The valve 4. is equipped with a centrally disposed conduit orpassageway 5 adapted to oaline with the conduits 1 and 2 when turned at the proper angle thereto.

The rotary valve '4 is" equipped with a reduced neck. 6 that is adapted to form with the body of the valve 3 a shoulder 7 and an annular flange 8, in such manner that there is made a chamber at 9 located between the surface of the neck 6 and said ,fiange 8. Said valve 4 is, assembled in'its casing 3 and locked in such position'by an annular ring 10 that is split for assembling purposes and provided-with apertures111l for the insertion of the teeth of aspanner wrench. Two corresponding apertures 11,

11 are made in the top of the valve 4 and are adapted to aline with apertures. 11, 11,

when valve 4 is in open position, whereby the teeth of the spanner wrench may reach said apertures 11, 11. Between the lower edge of the ring 10am the shoulder 7 0f the valve 4 is disposed an annular washer 12that has convolutions 13 adapted-to exert a pressure against the shoulder 7 in order to hold the valve v4 in a tight fitting manner within its tapering aperture of the casing 3. It will be noted, that thelocking ring 10 is located in such position thatit cannot be tampered with by unauthorized persons.

The lowermost surface of the valve 4 has formed thereon in an integral manner, a flange sector 15 that-is equipped with a shoulder. 16 and an opening17 for cooperation with the end 18 of a bolt 20' of a Yale or other similar locking device 21 located in a chamber 22 formed in the lower part of the casing 3.

A spring 25 that has a bearing in a recess 26 formed in one end of the bolt 20 is adapted to urge said bolt 20normally against the surface of the flange 15,

whereby theend 18 of said bolt 20 will en:

gage automatically the opening 17 to lock will engage the shoulder 19, whereby to stop the turning of the valve 4 in closed position and will engage also the shoulder 16, whereby to stop the turning of said valve 4 in full open position. The valve 4 is turned automatically into full open position by a coiled spring 30 that is attached at one end to an arm 31 formed integral with the upper flange 8 of the valve 4 and at the other endto arniember'attached to the outer casing of conduit 2. V The bolt QQ is actuated against the spring 25, whereby to retract the-end 18 from the opening 17 by the correspondingly formed f member 35 ofthe Yale lock 21, which bears r by "pulling upon the end of a cord 37 that is against the upturned flanges 36-36 formed integral with the bolt 20.- ;The turning of said lock 21 will rotate the member 35 which will press against either flange" 36 in either direction of rotation of said member 35 to, thereby, retract the bolt 20.

The operation of the valve lock is effected when'the automobile is stopped temporarily located near the seat of the chauffeur, the

other end of said cord'37 being attached to the arm 31 of the valve 1, whereby to rotate said valve 1 against the pull of the coiled spring in order to bring the opening 17 Yale lock 21 to,'thereby, turn the member inv order to, retract the end 18 of the bolt 20 from itshousin in opening 17. After the end 18 of the bo lt 20 is withdrawn from the tension' of spring 30. The contact of the end 18 of bolt QO WIlth the shoulder 16 of the flange 15 will stop the vvalve a automatically in full open position.

Said valve'casing 3 can be cast integral with the carburetter casing or with the intake manifold, whereby to eliminate the possibility of separation of said valve casing 3 from its assembled position with'reference to saidcarburetter and intake manifold by unauthorized persons. If said casing 3 is cast thus, it will become anintegral part of the motor mechanism, and, therefore, the

"more difficult to tamper with.

Having thus described my invention what I claimas new and desire to secure'by Let ters Patent is:

1. In a va ve loclrfor automobiles, a rotary valve having a reduced neck and an annular flange, a locking ring disposed within said chamber, an arm extending'from said valve, whereby it may be turned and automatically locked in closed position, and spring means for turning said valve to'open position. I i V a 2. In a valve lock for automobiles, a rotary valve having a reduced neck and an annular flange forming a chamber, a locking ring disposed within said chamber, means for limiting the turning of said valve in'either 7 open or closed position and aloe]: for holding said valve in closed position, whereby to prevent the passage of gas to the engine of said automobile; V I p 3. In a valve lock for automobiles,a casing having a tapered aperture, a rotary valve adapted to turn in said aperture, a

flange sector having a shoulder and opening formed therein and a spring actuated bolt 7 adapted to cooperate with said opening in the'flange sector, whereby to lock said rotary valve in closed position. I i

et. In a valve lock for automobiles, a casing having a tapered aperture, a rotaryvalve having an overhanging annular flange, said valve being adapted toturn in said tapered aperture, a' flange-sector 'wlth a shoulder and opening formed therein, a

spring actuated bolt adapted to cooperate .1

with said opening in the flange sector,

"whereby to lock the rotary valve invclosed position, a key for withdrawing said bolt from the aperture, whereby to allow the valve to-turn automatically to open position.- opening 17,: the valve 1 will rotate autoniatically into full open position under the a chamber, adapted to turn in said aperture,

a loekingring disposed in said chamber, an

annular washer having convolutions adapt- 7 ed to hold the valve in a tight fitting manner in the first mentioned tapered aperture, a flange sector with a shoulder and opening formed therein, a I spring actuated bolt adapted to cooperate with said opening in the flange sector, whereby to lock the rotary valve in closed position, and a key for withdrawing said bolt from the aperture, where by to allow the valve to turn automatically:-

toopen position.

In testimony whereof I have aflixed my signature. I

GEORGE H. HARRIS.
